Title:	Motor issue

Today again, same problem with axis 9 blocking the controlling software during the mirror alignment procedure.

after opening the motor 9-16 controlling crate, we saw 2 screws (RX- and TX+ of the controller) which were badly screwed.

we firmly screwed them... could it be the cause ?

after reconnecting everything, the software launches properly... and everything is back to work... wait and see.

Today, Axis 9 (Z-axis of P1) has blocked the software which drives all the motors.
impossible to bypass the problem.

I had to :

- switch off the motor driver crate n°2 (motors 9-16)

- disconnect all motor cables (9-16)

- reconnect only cables 15 and 16.(same internal board of crate n°2)

- restart the software to test that, now, the software launches properly

and I did again the procedure with connecting all motor cables
